N538EP High-Performance Sub-1GHz USB Dongle Adapter(433MHz Model)
Product Overview
The N538EP is a versatile, high-performance USB radio dongle designed as a universal development and testing platform for key Sub-1GHz ISM bands. This model is optimized for the 433 MHz band. It integrates the advanced Texas Instruments CC1314R10 wireless microcontroller—a leader in multi-protocol support—with an efficient Power Amplifier (PA) to deliver a robust +24 dBm output. Enhanced by a high-stability TCXO and industrial-grade construction, this dongle as an ultimate plug-and-play tool for developing, prototyping, and validating IoT, smart utility, and industrial wireless solutions in the 433 MHz spectrum.
Key Features & Benefits
✅ Multi-Protocol Flexibility on a Scalable Platform: Leveraging the multi-protocol CC1314R10, this dongle is a perfect development platform for the 433 MHz band. The common hardware design supports variant models covering other key frequencies (e.g., 868, 915 MHz), offering a unified development experience across protocols like Wireless M-Bus, Wi-SUN, 6LoWPAN, and proprietary systems via TI's SDK.
✅ High-Power, Reliable RF Performance: +24 dBm transmit power and excellent sensitivity ensure strong, reliable communication links over distances up to 1500 meters, overcoming common range limitations in field deployments.
✅ Carrier-Grade Frequency Stability: Integrated Temperature-Compensated Crystal Oscillator (TCXO) provides precise frequency control (±1 kHz), which is critical for timing-sensitive protocols and dense network deployments.
✅ Industrial Robustness: Built to operate reliably in harsh environments with an extended temperature range of -40°C to +85°C and a professional 4-layer PCB design.
✅ Complete, Ready-to-Use Package: Comes with a user-programmable button, status LED, integrated spring antenna (plus IPEX connector), and debug access. Presents as a standard Virtual COM Port over USB for immediate use.
✅ Future-Proof Development Platform: The powerful CC1314R10 offers ample processing power and memory to run complex protocol stacks, making it ideal for developing sophisticated gateways and network managers.
